Vulnerability AssessmentAI

Risk Assessment	The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) indicates network-accessible, low-complexity exploitation requiring low privileges (authenticated user) with limited impact scope (confidentiality, integrity, and availability each at low level). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An authenticated user (or attacker with stolen credentials) navigates to the supplier view page and submits a POST request with a crafted SQL payload in the searchtxt parameter—for example, searchtxt='; DROP TABLE suppliers;--. The PHP application concatenates this directly into a SQL query without escaping, causing the injected SQL command to execute against the backend database. …
Remediation	The primary remediation is to contact SourceCodester for security updates or upgrade to a patched version if available via https://www.sourcecodester.com/. … Detailed patch versions, workarounds, and compensating controls in full report.
